Litiyumu - ion ya bateri ya electrode iranyerera ni iki?
Uburyo bwa elegitoronike
Gutemagura byitwa kogosha mugutunganya imashini, kandi ukurikije uburyo bwibikoresho byo gutema, birashobora kugabanywa muburyo bwo kogosha nka oblique - kogosha icyuma, kuringaniza - gukata icyuma, gukata kuzunguruka (cyangwa gukata umuzingo), no gukata disiki.
Muri oblique - kogosha icyuma, hari inguni ihamye hagati yicyuma cyo hejuru nu hepfo, kandi inguni ihindagurika ni dogere 1 ~ dogere 6. Mubisanzwe, icyuma cyo hejuru kiragoramye, nkuko bigaragara ku gishushanyo 7 - 2 (a). Kubera ko ibyuma byo hejuru no hepfo bidafite aho bihuriye, hari imbaraga zijyanye no guca inzira, byoroshye kugoreka impande zaciwe. Nyamara, agace kogoshesha ni nto, kandi imbaraga zo kogosha no gukoresha ingufu ni ntoya kuruta iyogoshesha icyuma -, bityo rero ikoreshwa mugukata amasahani manini mumashini manini kandi manini yo kogosha, kandi mubisanzwe ntabwo akoreshwa mugucamo electrode.
Kogosha Flat - gukata ibyuma bifite imiterere imwe nkiyogoshesha - gukata icyuma, usibye ko impande zo hejuru no hepfo zisa, nkuko bigaragara ku gishushanyo 7 - 2 (b). Igera ku gukata nta kugoreka kandi ifite ubuziranenge bwo gukata, ariko imbaraga zo kogosha ni nini, kandi ikoreshwa cyane mu mashini zogoshesha no gukata amasahani yoroheje na firime [1-2], ndetse no gukata electrode.
Gukata rotary byitwa kandi arc - gukata uruziga, rukoresha ibikoresho hamwe na arc -. Ibikoresho byuzuza uburyo bwo kogosha mukuzunguruka no kuzenguruka amashoka abiri ahamye, nkuko bigaragara ku gishushanyo 7 - 2 (c). Byakoreshejwe cyane cyane kugirango tumenye neza - uburebure bwambukiranya - gukata, umutwe n'umurizo byambukiranya, no kunyerera. Mubisanzwe, iyo yogoshe amasahani aringaniye kandi yimbitse, agaragaza ubuziranenge, gukoresha ingufu nke, kuramba, no gusohora cyane [3].
Gukata disikuru byuzuzwa no guhinduranya kuzenguruka kwa disiki ebyiri - zifite ibiziga bikata, imwe hejuru n'indi munsi, nkuko bigaragara ku gishushanyo 7-3. Mugihe cyo kogosha, urupapuro rwa electrode rudafunze rwinjira mugukata disiki kandi rugabanijwemo imirongo myinshi nyuma yo gukata [1]. Gukata disiki bikoreshwa cyane muburyo bwo gutobora amasahani yoroheje, firime yoroheje, hamwe nicyuma.
Mu gukora bateri ya lithium - ion, gukata birebire (gutemba) kumpapuro za electrode mubisanzwe bikoresha kogosha disiki, mugihe umusaraba - gukata ukoresha kogosha -. Imirongo itanga umusaruro isanzwe ikora mbere, hanyuma ikambuka - gukata. Mubisanzwe, ibikurikira bikurikira bishyirwa kumurongo wa lithium - ion ya batiri ya electrode:
Accuracy Urwego rwo hejuru rwerekana urupapuro rwa electrode;
Urupapuro rwa electrode iringaniye kandi idafite burrs, ifite inenge nke, kandi igipande cya electrode nticyangiritse;
Umusaruro mwinshi no gukora neza.
Amabati yo Kogosha Amashanyarazi
Kubikoresho bya pulasitiki, uburyo bwo kogosha bushobora kugabanywamo ibice bitatu [5-6]:
① Icyuma gitangira gukanda mu isahani, kandi ibikoresho byo mu isahani hagati yo gukata bigenda bihindagurika kandi bigatemba kugeza igihe ingano ya plastike igeze ku mbibi za plastike. Ibi byitwa icyiciro cya mbere. Muri iki cyiciro, ibikoresho by'isahani byogoshe, bikora ubuso bworoshye, reba Ishusho 7-4 (a).
② Icyuma gikomeje gukanda mu isahani, kandi kigacika nucleate, ikwirakwiza, kandi ikinjira mu bikoresho by'isahani hagati yo gukata. Ibikoresho by'isahani hagati yo gukata bigenda bitanyagurika bitewe nigikorwa cyo guhangayika kugeza igihe ibyuma byo hejuru no hepfo biri kumurongo umwe utambitse. Ibi byitwa icyiciro cya kabiri. Muri iki cyiciro, isahani yatanyaguwe, ikora ubuso butavunitse, reba Ishusho 7-4 (b) na (c);
Icyuma gikomeje gukanda hasi. Bitewe no gutembera kwa plastike, ibikoresho bya plaque hagati yo gukata bisohoka mu cyuho gito aho ibyuma byuzuzanya. Mugihe guhuzagurika gukata icyuma byiyongera, ibikoresho bya plaque mu cyuho birashwanyaguritse kandi bikururwa, bikora burr ku nkombe, reba Ishusho 7-4 (d), kugeza ibikoresho bitandukanye. Ibi byitwa burr gushiraho icyiciro. Mugihe cyo gutandukanya ibikoresho, ibikoresho bizagira ingaruka zoroheje cyangwa zisohora ibintu kubisahani, bigatera morphologie yubuso butavunitse kandi burrs ihinduka, ariko impinduka ni nto.
Umusaraba wogosha - nyuma yo gukata werekanwa ku gishushanyo cya 7-5, kigizwe nibice bitatu: ubuso bworoshye bwogosha, ubuso buvunitse butagaragara, hamwe na burr burr [5-6]. Ubuso butavunitse bwitwa nanone kuvunika kuvunika. Ubugari bwacyo bujyanye na plastike yibikoresho. Kubikoresho bifite plastike nziza, ubuso bwavunitse bwijimye ni buto, ubuso bworoshye bwogosha ni bunini, kandi icyuma gitemba ni kinini, bigatuma gikunda cyane. Ibinyuranye, kubikoresho byoroshye, nta buso bworoshye bwogosha.
